Abstract

A radiation image detecting system includes a solid radiation detector made up of a plurality of solid radiation detecting elements which are two-dimensionally arranged and convert radiations bearing thereon image information to an image signal. An A/D convertor converts the image signal as output from the solid radiation detector to a digital image signal. The digital image signal is analyzed and a characteristic of standardization processing which is to be carried out on the digital image signal is determined. A standardization processing circuit carries out standardization processing on the digital image signal according to the characteristic of standardization processing determined.
